Abstract:

This talk will provide a technical overview of PNDetector’s capabilities in Silicon based X-ray detection, with a particular focus on our pnCCD-based Colour X-Ray Camera (CXC). After a brief introduction to the company and its development of silicon-based detectors, the presentation will outline the design principles and performance characteristics of the pnCCD, a fully parallel-readout, energy-sensitive imaging sensor originally developed for space and XFEL applications.
The CXC system integrates this technology into a compact platform capable of simultaneous spatial, energy and time-resolved X-ray detection. It offers 264 × 264 pixels at 48 µm pitch, frame rates up to 10,000 fps (in windowing mode), and an energy resolution of 145 eV at Mn Kα. Variants include both standard and annular sensors, the latter supporting central-beam geometries for combined or in-line techniques.

Application examples will be presented, including Full Field XRF Mapping (FF-XRF), energy-dispersive XRD mapping, and polychromatic SAXS. These demonstrate the suitability of pnCCD detectors for multi-modal, high-throughput experiments, particularly in synchrotron and laboratory environments where simultaneous spatial and spectral data acquisition is beneficial, unlocking new data analysis possibilities or increasing throughputs over traditional techniques.
